Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If electromagnetic waves are irradiated using initial focusing parameter, then treatment efficiency is improved, but unnecessary focusing points occur causing side effects
Solution Approach 1:
The system performs preliminary temperature change prediction and unnecessary focusing point detection before actual electromagnetic wave irradiation. By analyzing the numerical model and predicting temperature distribution in advance, the system identifies potential harmful focusing points and adjusts focusing parameters beforehand to prevent side effects from occurring
Solution Approach 2:
The system uses predicted temperature change information as feedback to optimize focusing parameters. The temperature prediction results are fed back into the parameter optimization process, allowing the system to adjust focusing parameters based on predicted thermal effects and eliminate unnecessary focusing points that would cause side effects
2Reliability
If focusing parameter is optimized to prevent unnecessary focusing, then safety is improved, but system complexity increases
Solution Approach 1:
The system introduces a numerical model as an intermediary between the electromagnetic wave irradiation system and the patient's body. This virtual model allows for safe simulation and prediction of temperature distribution without directly irradiating the patient, enabling complex safety optimizations in a computational environment before applying simplified parameters in practice
Solution Approach 2:
The system replaces complex iterative trial-and-error physical testing with computational electromagnetic analysis and temperature prediction. By using numerical simulations and mathematical models to predict focusing effects, the system avoids the need for repeated physical adjustments and measurements that would increase system complexity and treatment time
